STAR-DRILL LIQUID
STAR-DRILL LIQUID is a high-molecular-weight, anionic liquid polymer designed to provide cuttings encapsulation and shale stabilization, and also acting as a viscosifier, friction reducer and flocculant. STAR-DRILL LIQUID can be used in both fresh and saline make up water
Application
STAR-DRILL LIQUID polymer systems provide excellent cuttings encapsulation and improved wellbore stability in fresh, weighted, KCl or NaCl enhanced fluids. Clear-water fluids. STAR-DRILL LIQUID may be used in clear-water, solids-free drilling fluids. It increases viscosity and removes solids by flocculation. Low-Solids, Non-Dispersed (LSND). In reduced- bentonite fluids, STAR-DRILL LIQUID acts as a bentonite extender to increase viscosity, flocculates drill solids for more efficient removal. STAR-DRILL LIQUID viscous sweeps are effective for periodic hole cleaning
Advantages
- Provides excellent cuttings encapsulation and limits cuttings dispersion
- Provides improved shale stabilization
- Enhances the removal of drill solids
- Mixes and yields easily
- Aids in preventing balling on the bit, stabilizers and bottom-hole assembly by coating and lubricating solids
